Acta Crystallographica Section E Structure Reports Online, 2009 Two enantiomeric counterparts (l- and d-asparginium cations related by glide planes) are present in the structure of the title compound, C4H9N2O3+·ClO4−, with a 1:1 cation–anion ratio. The structure is built up from asparginium cations and perchlorate anions. In the crystal, mol ecules assemble in double layers parallel to (100) through N H · O, O

Hexacarbonyltechnetium(I) perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 The title compound, [Tc(CO)6]ClO4, was synthesized by the reaction of [TcCl(CO)5] with AgClO4, followed by acidification with HClO4 under a CO atmosphere. The [Tc(CO)6]+ cation has close to idealized octahedral geometry, with the bond angles between cis-CO groups close to 90° and the Tc—C bond lengths in the range 2.025 (3)–2.029 (3)Å.

2-Chloroanilinium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the crystal of the title compound, C(6)H(7)ClN(+)·ClO(4) (-), a layer-like structure parallel to the bc plane is formed through N-H⋯O hydrogen bonds between the cations and anions. These layers are connected by weak C-H⋯O inter-actions, forming a three-dimensional network.

2,6-Diethylanilinium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 The asymmetric unit of the title mol-ecular salt, C(10)H(16)N(+)·ClO(4) (-), contains two cations and two anions. The atoms of one of the ethyl side chains of one of the cations are disordered over two sets of sites in a 0.531 (13):0.469 (13) ratio. In the crystal, the components are linked by N-H⋯O and bifurcated N-H⋯(O,O) hydrogen bonds and weaker C ...
